Am I (we) deluding ourselves?
I also think that your choice is a valid one :D Just before buying the K5, whilst I had no intention of changing system I decided to look at the competition to see what if anything could change my mind from a K5 and below is what I found, this is my opinion and not a snipe at anything. Canon -...

Am I (we) deluding ourselves?
One problem I see is similar to how all of the Spectrums, BBC computers etc. fared against the 'pc'. Because of the popularity of the 'pc' massive amount of software became available, lots of hardware add ons and updates were produced making it even more popular and even more useful and cost effecti...

You can't be 100% sure that new 24Mbpix sensor will have worse noise performance than 16Mbp, I know logic says so, obvious, but couple of years ago people used to say similar for 10-12Mb vs 16Mb and then were surprised by how well/better 16Mbps found in D7000, K-5 performs :). To be honest I can'...

There are some benefits to more MP which has become apparent with the Nokia 808.... Pixel binning. Currently sensors use one pixel per colour and take a guess at what the final colour of each pixel should be. the Nokia 808 uses it's 41MP sensor to provide for a very detailed 8MP image. Maybe DSL...

I've noticed a trend in reviews recently, when assessing new sensors over the 20MP level (but not Full Frame), to draw attention to various consequences in other areas - in particular higher iso noise, and of course higher prices, so its not all gain gain gain. And of course the marketing people pus...

Increases in sensor technology should allow for better higher ISO noise even with higher pixel counts. The 16mp K-5 sensor had about 3 stops better performance over previous less MP sensors. this is generally true, especially in the case of your example. But expectedly the K-3 will get the sensor of...

I would expect the K-3 as anticipated above, if it had the same sensor as the A77, to perform better in terms of ISO/noise. The reason is that SLT camera lose 30% of their light to the EVF, meaninf they need more amplification to give the same exposures. Therefore, noise will be higher, all other...

If the specs are true, because I lean towards more wildlife & sports photography I think I'd take the K5N before the K3, a K5 with better AF is all I need. Hopefully my K5 grip would fit too. I can't see a 24MP cropped sensor being better noise wise than a K5 and my PC struggles with 16MP images in...

I wouldn't be surprised if the K5 II is real, but I think after two years they need to bring out something better than a simple upgrade. I'd be surprised if there's nothing with the Sony 24MP sensor in it.

I'd be surprised if there's nothing with the Sony 24MP sensor in it. I'm beginning to think that Pentax should have used the 24MP sensor in the K30 - that would have been a shot across the bows of Canikon:twisted:

And to be strict it is not that something is taken out (at least based on Nikon D800E example), just another filter in front of sensor reverts what the first filter did (vs splitting light on other plane as well as with conventional model). We'll see what the camera will be like in real life, but j...

Fair play to Pentax for sticking with 16mp - I dont want larger file sizes and a buffer filling up twice as fast where the upside is higher resolution I don't really need (how many actually do NEED more than 16mp?). At 16mp the limiting factor is the lens resolution, you would need a bigger sensor t...

[quote:3496ace15f="japers45"] At 16mp the limiting factor is the lens resolution, you would need a bigger sensor than APSc for 24mp, hence Pentax have rightly stayed with 16mp so have Nikon as far as I know with the D7000. John Hasnt stopped Nikon with the D3200 and Sony with the NEX7 and Alph...

[ Hasnt stopped Nikon with the D3200 and Sony with the NEX7 and Alpha range. The D7000 is as old as the K5 (mark 1!)so any D8000 may have higher MP count. Pentax will go 16mp + on APSC at some point I reckon. Primarily because the miopic amongst us regard more MP as better. Sad but true. Ah well, ...
